The epic games launcher got an update today and when ever I try to update, I get this Error SU-PQR1603.
I did some googling and I found that you just need to add -SkipBuildPatchPrereq lunch argument.
But lutris already has this in by default.
Running: WINEPREFIX=~/Games/epic-games-store WINE=~/.local/share/lutris/runners/wine/ge-protonified-4.9-x86_64/bin/wine ~/.local/share/lutris/runtime/winetricks/winetricks dotnet48
Fixed the issue for me. After getting dotnet 4.8 installed, Epic games launcher was able to complete the update successfully.
Can confirm that this works without a complete reinstall. Just used winetricks to install dotnet 4.8. Still got some kind of dll error message but it’s up and running without any other issues. Thanks for the quick fix, @jdjb
